Abstract

Article history: The In S nano-flower films on TiO /FTO (Fluorine-doped tin oxide) substrates were synthesized via 2 3 2 Received 8 December 2015 hydrothermal method and the photoelectrochemical performances of In S /TiO photoelectrodes were 2 3 2 Received in revised form 1 February 2016 characterized. The roles of PSS (poly(sodium-p-styrenesul-fonate)) and PEG (polyethylene glycol) on the Accepted 4 February 2016 structure controlling of In S films were also discussed. The results show that the In S nano-flower films 2 3 2 3 Available online 17 February 2016 consisted of ultrathin nanoflakes with a thickness of 5 nm are successfully grew on the surface of TiO nanorod arrays.
